IMPROVEMENT IN DIES FOR MAKING COLLARS.

To all whom it may concern:

Beit known that I, GEORGE K. SNOW, of

Watertown, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Dies for Making Collars,of which the following' is a specification The object of my invention isthe application of diesto the process of cutting collars from a strip ofmaterial having paralleledges and of a width but little in excess of thesum of the greatest and least widths of the collars to be produced,arranged and operating in such a manner that at each downward movementof the cross-head each pair of dies shall shape the contiguous ends oftwo collars and about one-fourth part of the length of the bottom edgeof the same collars, and about onehalfl the length of the bottom edge ofanother collar, said half length cut being the middle portion of thelatter collar, and also at the same movement of the cross-head to punchthe end button-holes in the two collars whose ends are being shaped, andthe middle buttonhole in the contiguous collar whose middle is beingshaped by said movement. Two sets of dies are used, arranged to cut oneupon either edge of the strip of material, and each die cutting out thewaste between the contiguous ends of two collars, and also cuttingbetween the contiguous bottom or top edges of a portion of three collarsa distance equal to at least half the length of the longest collar. Thesame movement of the cross-head also embosses the imitation stitching ontwo collars and the line of fold on two others. The

' distance between the centers of the two pairs of cutting-dies is adistance a little greater than the length of a collar and a half, and asthe material is fed forward a distance equal to the length of a collarit follows that after the third or fourth stroke two collars will becompleted at each stroke of the cross-head. This application illustratesone mode of taking advantage of the circumstance of the middle of acollar being narrower than the ends in order to make a savinginmaterial, as described in another application of even date herewithforimprovements in the manufacture of collars; and although I waste a pieceof stock between the bottoms of two collars I still make a great saving'as compared with the present mode of cutting collars.

l Figure I is a plan of the lower or bed dies. Fig. 2 is a section online :c fr on Fig. l. Fig.

3 isa plan of the under side of the upper or 'I movable die. Fig. 4. isan edge view of the same 5 and Fig. 5 is atransverse section on line z zon Fig. 3. Fig. 6 is a plan of a strip of material in process of beingcut into collars.

A is the bed-plate of the lower' or female die, having a dovetailedgroove planed or otherwise formed therein to receive the plate B, towhich are secured the most ofthe parts 'which constitute the femalecutting-die and the lower embossing-dies. The female cuttingdie is madeup of several pieces of steel plate, as C and C', which are the reversecenter parts of each other, each being shaped like the ends of thecollar that is to be cut, and having' formed therein the female die afor cutting the end button-holes. l) is another steel plate, one vedgeof which is shaped to the form of the middle portion of the lower edgeof the collar, and having formed therein the female die b for cuttingthe middle button-hole. E is a plate one edge of'which is curved to theproper shape, and provided with a blunt knife-edge or male-die, c, forembossing the line of fold upon a collar, said die being of a lengthequal to the length of the longest collar. F is a plate of eventhickness with the plates C, and made to fill the space between theplates C and E ofthe two dies and form a surface upv on which theimitation-stitching is embossed. G G are plates of metal, secured byscrews or otherwise to the bed-plate A in a position parallel to eachother, the lower corner of the inner edges beingv cut away so as to formgrooves to guide the paper while being fed through the machine. Theplates B extend toward each other a distance equalto threefourths thelength of the shortest collar and are adjustable toward or from eachother, a filling piece being placed between them of suitable length tolocate the cutting-dies at.

the proper distance apart to cut the desired collar. The bed-plate A issecured firmly to the bed of the machine. H is the bed-plate of theupper die, and is secured rmlyto the cross-head of the press in which itis to be used, in any suitable manner, directly over PATENLQFLIGE.

the lower die in such a position that 'the pins d will tit into theholes e in the lower die. I I are guide-plates secured to the bed-plateH by screws or otherwise, and having their inner edges beveled so as toform a dovetailed groove, into which are fitted the plates J, J1, andJ2, upon which are secured the several parts of the cutting andembossing dies. K and K are the male cutting-punches, which cut out thewaste stock betweenv the ends of two contiguous collars and shape themiddle portion of the lower edge of one collar and the end portions ofthe lower edge of two other collars. h h are the male punches, whichwork in conjunction with the female dies a a to cut the endbutton-holes; and t' i are corresponding dies, to work with the femaledie b to cut the middle button-holes. L L are plates having one edgecurved, and also having a curved groove, o, formed in the face thereof,which, working with the male die c, embosses a curved line upon thecollar to determine the fold. M M are the male stitching-dies, soarranged as to emboss the stitching on two collars at every downwardmovement of the upper die.

rlhe male cutting-dies may be adjusted with relation to each other byremoving the plate J1 and substituting for it another one of greater orless length, according to the size of the collar to be made. The stitchembossing-dies M and F have to be changed for every different size ofcollar made, and the fold embossing-dies have to be changed about everytliird size. The form of the dies may be so changed as to cut betweenthe ends of two contiguous collars and the top edges of portions ofthree collars, instead of cutting between the bottom edges, as abovedescribed, if it is desirable toV cut a collar having a curved-top edge.

Itis evident that the strip of material may be fed automatically to thedies by providing a means of discharging the collars after they are cut.Openings should be made in the bedplate A immediately under the femaledies to allow the waste which is punched out to fall through, saidopenings not being shown in the drawing.

The operation of cutting collars and embossing the same by this processis as follows: The material is irst cut into strips of even width havingstraight parallel ed ges, and then said strips are 'fed endwise betweenthe cutting and embossing dies, the edges of said strip being guided bythe grooves formed in the under sides of the plates G Gr, the forwardend of the strip being placed at the dotted line y y, when thecross-head carrying the upper die descends, and the right-hand die willpunch out the waste indicated at m in dotted lines, theimitation-stitching will be embossed on the partof a collar marked n,and the foldline will be embossed on the. collar marked o, and the threebutton-holes,marked r 'r1 r2, are cut. .When the cross-headrises thematerial is fed forward to the left a distance equal to the length of acollar, when the cross-head again descends and the right-hand die cutsout the waste indicated by full lines ats, Fig. 6, and the left-hand diecuts out the waste in dicated in full lines at t. Theimitation-stitching is embossed on the collars u and o, and the line offold embossed on the collars n and n1, and each set of dies will cut twoend buttonholes and one center button-hole, and the two parts of collarsn and n2 will be severed from the strip.

The operations above described being repeated, two collars will besevered, two `will have imitation stitching embossed thereon, and twolines of fold will be embossed on two other collars. In other words, twocollars will be completed at each downward stroke of the cross-head,portions of the work being done upon six collars at the same time. Thesame.

work may be done with a single pair of dies by feeding the strip ofmaterial through twice,

'the material being turned around so as to cause the dies to act uponthe other edge thereof. By means of this arrangement one cutting-die maybe made to shape all the different sizes of` collars of a given stylewithout change oradjustment thereof.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. A cutting-die so constructed and operating as to shape the contiguousends of two collars and at the same time shape about onefourth part ofthe length of one edge of each of said two collars and about one -halfthe length of one edge of another collar, the middle of which isopposite to the ends of the two collars first named, substantially asdescribed.

2. In combination with a cuttingdie ar` ranged to shape the contiguousends of two collars and the middle portion of a third, I claimbutton-hole dies so arranged and working therewith as to cut two endbutton holes `and one'center button-hole, each" in separate collars,substantially as described.

3. In combination with a cutting-die arranged to shape the contiguousends of two collars and the middle portion of a third, I claim astitch-embossing die so arranged in connection therewith as to emboss animitation-stitch on one of said collars, substantially asl described.

4.. In combination with a cutting-die arranged to 'shape the contiguousends of two collars and the middle portion of a third collar, I claim apair of embossing-dies so ar ranged in connection therewith that thesame movement which shapes portions of three collars shall emboss theline of fold on one of said collars, substantially as described.

5. I claim the within-described arrangement of shaping-dies, button-holeand embossing dies, by which portions of three collars are shaped, abutton-hole is formed in each, a line to determine the fold is embossedon one, and an imitation stitch is embossed on another of said collarsat one movement of said dies, substantially as described.

tiguous ends of two collars and portions of the tops or bottoms of threecollars, when so formed that each successive operation of the same uponopposite edges of a strip of paper or other suitable material shallsever a oompleted collar, substantially as described.
